I just got two Asus 5850’s a couple of weeks ago from Newegg, the default settings are 850/1200 and the BIOS appears to be the same version as the 5870 according to GPU-Z. Also Asus Smart doctor doesn’t recognize the cards which may indicate they have the 5870 BIOS. Has anyone else seen this with new out of the box cards?

What is a safe temperature for both the VDDCs and the GPU? I'm running my 5850 stock 725 core 1000 mhz mem. But for gaming, I'll turn it up to 870 core 1080 mem with @ max voltage of 1.1000
This was FURMARK TEMPS
The gpu maxed out @ 83c
vddc1 max 92c
vddc2 max 94c
vddc3 max 91c
Furmark stability test is hardcore!
In Game BFBC2 1680X1050 graphics on high settings
GPU max 41c
vddc1 max 39c
vddc2 max 39c
vddc3 max 39c
I would imagine that I could OC some more for games.
I've found that 850 core and 1140mem is very game stable at 1.1v and temps are good at 51c
ive got prob with Smart Doctor. Everytime after i restart system it sets V to 1.6v - 1.5v - any idea how to fix it?
I found on ASUS support site drivers for 5850 - if im gone install these r thay gone replace ATi drivers or its just some kind od addon. Any1 tryed tham?
I'd like to revisit using RBE to modify core voltages. Do you edit register 0x17 and then use the number you put in there as well for the core state voltages? Alternatively, do I leave the core state voltages clear or use the value corresponding to the default voltage of that register, etc? When I tried modifying the voltage on my 5850, it didn't work.
Don't use that.Quote:

@ Frogeye: ramp up the fan for furmark, can leave it on auto when gaming, and push the card higher.
@ Particle: you need to change the register value only I think. Link.
Success. I left the voltages alone in the GPU xx table and then just changed all four registers to 1.2V since I don't care what "state" it is in (I want it locked to 3D clocks at all times).
Still testing but I've got the card two hours stable gaming @Quote:

Today I'm going to go with 930/1100 and that should be that. :up: Unless you think I could try something different.
Regardless the card rips it up at this OC. TY!
So far so good at 900/1150 using 1.2V. :up: Hoping for 1000 before all is said and done.

Did some benching yesterday with the computer in front of the Window. Wasn't that cold though. Hopefully we can get some colder weather because I know i can push it farther
Yeah I got one of these from Newegg and I thought the card was flashed with a 5870 bios and returned so I sent it back. My buddy got one right after and he had the same thing so it looks like they are coming from the factory flashed like that. The second one I got after the rma was normal 725 clock.Quote:

ok, nevermind. flashed & done. .bin works
When I got booted back into windows & started to install 10.2 driver, it blue screened on me and dumped (need to turn that off, lol) then I got it back up ok. tried to install again after making sure to uninstall whatever did get installed. It then said the driver wasn't installed right. So I double checked the uninstall, rebooted and then Installed it finally.
it worked & is working now with 10.2 drivers
Is anyone having issues oc'ing with MSI Afterburner in Crossfire after cat 10.2?
When I apply clocks it just hangs when CF is enabled, but works fine with CF disabled... I think it may have to do with the new powerplay settings in 10.2 and newer??
Any particular brand that seems to be doing better, have a choice between Sapphire and MSI, which one would you choose?
Both have the same warranty and MSI will be easier to RMA as I know the guys here. Asus is out, as the prices are about 20-25% higher for no reason.
Get MSI then.
No brand is doing better than others.
I got my asus 5870 for the same price has all the other reference boards! Tekheads sell them cheaper than normal if your in the uk!
what program are you guys using to overclock the 5870's? CCC? Been outta the ati game, is atitool still around? I have the ASUS version with voltage tweak, but i have to install their card driver to use the Asus Smart Doctor, and they dont have the new 10.2 yet.
MSI Afterburner all the way! :up:
My 5870 does GDDR5 5600MHz :eek: on Stock Voltage, i'm testing...
nice clock 4 memory, it's mean 1400 mhzQuote:

Using upto 1.3v using MSI software did not help at all...could it be that the voltage is locked? Which is the best bios to use now.
Also has anyone changed the TIM on these things...any reason to do so?
from what I hear the newer revision Sapphire 5800 cards have no voltage adjustment, but if you can access the voltage slider in AB chances are it's the older revision. The ones that I've tested that were the second spin, AB blacked out the slider.Quote:
